WINDOW-SCREEN.

SPECIFICATION forming part of Letters Patent No. 766,597, dated August 2, 1904.

Application led February 24,1904. Serial No. 195,058. (No model.)

` To all Ywhom it may concern:

Be it known that I, CHARLES H. Coiisrook, a citizen ofthe United States, and a resident of Indianapolis, in the county of Marion and State of Indiana, have invented a new and useful Improvement in Vindow-Screens, of which the following is a specification.

My invention relates to an improvement in window-screens; and the object is to provide a durable screen which will retain its shape, keep the wire taut, and which will have a neat and attractive appearance.

A further object is to provide a screen which can be easily applied to or removed from the window-frame.

Vith these objectsin view my invention comprises, mainly, a frame of wood the corners of which are suitably joined by mortising' or rabbeting, preferably, and bound together by a sheet-metal corner-piece which is preferably folded around the corner of the frame, entirely incasing and housing' the joints of the frame and protecting it from the weather, giving it strength as well as assisting in holding other parts of the screen, such as a spring and a tongue for retaining the screen in position in its movements in the window-frame.

My invention further consists in certain novel features of construction and combinations of parts, which will be hereinafter described, and pointed out in the claims.

In the accompanying' drawings, Figure l is a side view of the window-screen. Fig. Q is a section on line A A of Fig. l. Fig'. 3 is a perspective View of one of the corner-pieces. Fig. 4 is a View of the spring. Fig'. 5 is a View of another form of corner-piece adapted for holding the spring'. Fig's. 6 and 7 are the blanks from which the two forms of corner-pieces shown in Figs. 3 and 5 are formed, and Figs. 8 and 9 are edge views of the corner-pieces when folded.

O O represent the ends of the screen, and 3 3 the sides, they being mortised, rabbeted, or otherwise joined at their ends in order to form a neat and rigid joint. These corners are incased and housed by sheet-metal corner-pieces 4c a and O* O4. These corner-pieces may be variously constructed, although I have illustrated them 1n two preferred forms,

the blanks of which are shown in Figs. 6 and 7, and these two forms are for a special purpose. These corner-pieces consist of two leaves a a, the central web b, and flanges 2O 20. The two forms are practically alike, the only difference being that the flanges 2O 2O in one form embrace thc metal tongue 8, as shown in Figs. 2 and 9, whereas in the blank shown in Fig'. 7 they overlap each other, as illustrated in Fig. 8. The form shown in Fig. 7 is adapted to embrace and hold the spring' 6 upon the edge of the window-screen frame. The spring' 6 is held in the cornerpiece in any suitable manner-as, for instance, by means of a projection 7 on the spring', as shown in Fig. 4, which enters a hole AT in the corner-piece, as illustrated in Fig. 5-or the spring maybe held in place by an inwardly-extending projection on the co1'- ner-piece entering a hole in the spring', which is just the reverse of the other construction. The tongue and the corner-pieces are securely fastened to the frame by rivets or other means 9 9, extending through them and through the frame. The metal corner-pieces bind the frame, giving it strength and rigidity, protection from the weather, and at the same time two of them securely hold the springs in position, while the other two assist in securing' the metal tongue. rIhis metal tongue serves as a strengthener to the frame and also acts asa guide for the screen in sliding up and down. In other words, the metal corners serve to house and protect the cornerjoints from the weather and to make these joints, which in most screens are the weakest part and the lirst to loosen and open, the strongest part of the screen.

The numeral indicates a metal gutter which receives the edge of the screen having the springs. The numeral l0 is a bead having a rounded or beveled edge for the tongue 8 to ride upon and a groove 1l adapted to receive the tongue. In inserting' the screen the edge with the springs is first inserted in the gutter, the spring's being compressed sufficiently to permit the tongue 8 to clear the bead 10 until the groove l1 is reached, whei'eupon the tongue is permitted to enter the latter and the springs to expand to retain the IOO parts in position. To remove the screen, this operation is' merely reversed. In this way I provide a simple, strong, inexpensive, neatappearing, and effectual screen for excluding flies and other insects and at the same time one which can be easily raised or lowered and retained in position without interference to the ordinarywindow-sashes. Likewise and of the most importance the screen thus formed is strong and durable, the joints being incased and housed and fully protected from the weather, while at the same time they are braced and held securely.

This screen, made of hard wood, can be made of thinner stock than the ordinary screen, and

thereby be made to suit existing conditions met in houses previously built or without allowance of space for screens between the outer sash and outside blinds and provides a perfect screen without having to resort to the allmetal and more expensive screens.

It is evident that slight changes might be resorted to in the form and arrangement of the several parts described without departing from the spirit and scope of my invention, and hence I do not wish to limit myself to the exact construction herein set forth; but,

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. A window-screen comprising a` frame,

corner-pieces secured to the frame, a spring,

made rigid, a spring securely held by one corner-piece,and a runner received uponthe edge of the screen which carries the spring and inclosing the spring.

3. A window-screen comprising sides and ends, and metallic corners which embrace the corner-joints on both sides and edges, and are rigidly secured thereto, whereby the cornerjoints are inclosed and housed and protected from the weather, and the entire frame is made rigid, a spring securely held by one corner-piece, and a tongue held in the opposite edge of the frame, and embraced on opposite sides by iianges of the corner-piece, adjacent thereto.

4. A window-screen comprising sides and ends, and metallic corners which embrace the corner-joints on both sides and edges, and are rigidly secured thereto, whereby the cornerjoints are inclosed and housed and protected from the weather, and the entire frame is made rigid, a spring securely held by one corner-piece, a tongue held in the opposite edge of the frame, and embraced on opposite sides by flanges of the corner-piece, adjacent thereto, a runner adapted to receive the edge of the screen which carries the spring and a groove bead adapted to receive the tongue.

5. A window-screen provided with cornerplates, each plate comprising two wings adapted to embrace opposite sides of the screen, a web connecting the wings and embracing an edge of the screen, and flanges on the wings which engage another edge of the windowscreen.

In testimony whereof I have signed this specication in the presence of two subscribing witnesses.
